The Big Dutchman system for exhaust air treatment is the first exhaust air washer for poultry production which fulfils the requirements of the DLG Signum Test for a separation rate of ammonia and dust of at least 70 %.
Saves between 35 and 60 % of heating costs, improves the house climate and reduces emissions: approx. 30 % less ammonia, dust and odour emissions per year! In this regard please also refer to the DLG test results.
The heat recovery efficiency of the Earny heat exchanger for poultry houses is far above standard. Comprehensive tests under practical conditions in the context of the renowned DLG FokusTest have proven this. For the excellent test results see the test report available for download on the right.
